Since the tip is 15% of some cost x, we can calculate that.
Remember to write the percent as a decimal for the calculations
Think of the tip as the question 2.40 is 15% of what number?
2.40/x = 15/100
Multiply both sides by x
2.40 = 15x/100
2.40 = 0.15x
So the tip 2.40 = 0.15x
Divide both sides 0.15 to solve for x
And that makes the cost before the tip 2.40/0.15 = 16.00
$16.00
The total bill for his lunch would be the cost before the tip plus the tip
We can calculate the final bill as $16.00 + $2.40 = $18.40
Answer:
the answer is 4x and it is not equivalent becoz there should an answer of both sides equal
3D = 32 or D = (10 2/3)
Step-by-step explanation:
We want to make D only one side so we subtract 3D from the left
Then we slowly make the equation smaller and smaller by adding 24 to each side, multiplying the numbers, then finally getting our answers.
Answer = 196.34ML
If the length is 10cm and the diameter 5cm then the answer would be 196.34ML or 6.63 FL Oz
